Starter Turns but Engine Does not Start / Gear Selector Lever Cannot be Moved Out of Park Position "P" / Fault Codes B219116, B219600, B219700 Stored In Rear SAM
If you receive customer reports in the above model vehicles of the starter turning (cranks) but the engine may not start or the gear selector lever cannot be moved out of park ("P") position, this may be due to the no-load (quiescent) current switch (RSS) not functioning correctly. To remedy, follow the procedure below.
Note:
When this condition occurs, it is possible that Circuit 30g cannot be measured at the prefuse box preventing correct diagnosis of the SAM or actuation of the no-load current switch since diagnosis is only possible when Circuit 30 or 30g are present. You can connect a battery charger to ckt30/30g to pin 30/32 (reference WIS Document GF54.15-P-1256-07CE for proper pin outs) in order to use DAS for actuation and diagnosis. If any of these circuits are missing, it may be caused by inoperative RSS switch, a line signal/contact to the RSS switch broken or the rear SAM unable to actuate the no-load current switch.
Since the actuation of the RSS switch occurs only once when the vehicle is opened, or when the ignition is switched ON, the following steps must be taken first:
1. With ignition ON, measure circuit 30 at the input of the no-load current switch between pin 21 and 22, refer to Figure 1 (prefuse box where the measurements should be taken from). The measured voltage should correspond to the battery voltage.
2. Connect a load resistor to the battery, this will cause the no-load switch to open at voltage of 11.8 or lower.
3. Check the battery voltage, check circuit 30g at the output of the fuse box (Figure 1, pin 30/32) there should be 0 volts.
4. Switch ignition OFF: Place a load on a battery until the measure voltage is under 11.8 Volts, the no-load switch should now be actuated and open.
Prefuse Box and Signal Line Measurements: If the no-load current switch was opened by the rear SAM, the actuation of the no-load current switch can also be checked as follows.
1. Ignition ON, the no-load switch should be an audible switching "click".
2. If you can hear the switching click at the same time there is NO voltage across the output of the no-load current pins (30g voltage = Battery Voltage), replace the pre-fuse box
3. If no switching click is heard, continue with the signal line diagnostics and measurements as guided by DAS.
4. If all signal line diagnostics are OK, replace the rear SAM.
Prefuse Box Replacement: Since the fault cannot always be traced, even after actuation, prefuse box and signal line measurements, the pre-fuse box may be replaced only when the following faults/events are stored in the DTC memory of the rear SAM:
B219116: The power supply of circuit 30g is outside the valid range. The limit value for electrical voltage has not been attained.
B219600: The power supply of circuit 30g is less than 7.5 V.
B219700: The power supply of circuit 30g is less than 8.5 V.
Note:
Optimized pre-fuse boxes with index 28 manufactured as of November 19, 2008 should be used for replacement (Figure 2).
